Great for visibility but lacks many features and difficult to update
We're customers. We don't have a special relationship with the company. I am the operation's application administrator. At the moment, the solution is monitoring the applications that we want it to monitor. We're not looking at it on a daily basis. We just use it here and there. The challenge we have is that we believe that Dynatrace can address some tasks we'd like done that are not possible to execute on this solution. Dynatrace includes monitoring of not just the logs, but the applications as well. Dynatrace also makes us include firewalls, etc. We could have it so there are end to end solutions or identifications within the process. What we have right now is only the app server as well as the database server and its connectivity. The solution does save time that's caused when creating SQL coding. However, there are some issues around AppInternals changing the code and giving us issues. From the point of view of the top management, we want a more permanent solution. We want to identify what causes issues and we are looking for a more end-to-end solution. That is why we are looking at Dynatrace. I don't know if I have any advice for other organizations. The experience I have is only based on my own limited experience. However, I believe that the application has the potential to be really good if it identifies what is really important to an organization. It's still sort of half-baked without AppResponse. Without the other key features in infrastructure, like the network, firewalls, and proxies, it's lacking. It's not fully complete. I'd rate the solution six out of ten. It addresses some of our needs, but there's a lot lacking that could be added to make it a fuller, more interesting product.

Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"My advice to others would be to use this solution for monitoring."
"I like it that one can match IPs with the application name."
"The product is very useful to find problems in middleware for the application servers, especially agent instrumentation and management is user friendly."
"Clicks to root cause - fast & easy to diagnose and deep-dive"
"As an Administrator, before we bought this AppInternals, I didn't have visibility on why items were slow or why an application was not running. This gives us the ability to see what's going on. The application is load balancing. We can now see if its own server has issues or just one specific server has issues."
"The most valuable aspect of this solution is the integration with their other systems. It's easy to understand and it points out the relevant problems in the enterprise."
"Transaction Tracing is the most useful. Being able to have the transaction stitched together so we can see where the problem is has proven invaluable."
"Many times what might have taken hours or days can be resolved in a few minutes."
"Datadog is already covering much more than we normally need with exceptional quality."
"Datadog dashboards are pretty great."
"The solution is sufficiently stable."
"Watchdog is a favorite feature among a lot of the devs. It catches things they didn't even know were an issue."
"Session recordings have been the most valuable to me as it helps me gain insights into user behaviour at scale."
"Datadog has impacted my organization positively as this is our main observability tool when it comes to monitoring services, traces, and all resources within key services."
"The tools are powerful and intuitive to set up."
"The feature I have found most valuable is when I can reuse existing monitors and alerts for new dashboards."
 

Cons

"We have put in a request as an enhancement that we would like to search for items. If we're searching for a URL and we want to know was it a get or was it a post."
"It's still sort of half-baked without AppResponse. Without the other key features in infrastructure, like the network, firewalls, and proxies, it's lacking."
"The recording mechanism for synthetic transactions could be improved as well."
"I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it is now."
"It would be great if the solution could offer fixed bundles and more features."
"Support for PHP, DB and other applications need to be supported."
"Deployment and agent patch management is not managed centrally, resulting in a large level of effort to update."
"There are some functional bugs when using TTW and making report queries (to generate graphs)."
"The on-premise version is very difficult to upgrade."
"We have recently had a number of issues with stability and delays on logging, monitoring, metric evaluation, and alerts."
"The documentation leaves a lot to be desired for new users."
"The PagerDuty integration could be a little bit better."
"Graph filters for logs need to be set manually which works well for JSON but not for unstructured logs."
"I love to have some DD guru come in and do a department training directly at our setup."
"The documentation could be improved regarding setting up the agent properly and debugging."
"Some of the interface is still confusing to use."
 

Pricing and Cost Advice

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."
"The licensing model for v9 is better where it is an individual license per server, while v10 licenses are per JVM/ .NET and server instance. The latter model appears to be the model that other APM vendors are using."
"It has always scaled for us. Cost scales up too, but that is not necessarily a bad thing. It's reasonable for what they're providing."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"The solution's pricing depends on project volume."
"The pricing and licensing through AWS Marketplace has been good. It would be nice if it was cheaper, but their pricing is reasonable for what it is. Sometimes, for their newer features, they charge as if it's fully fleshed out, even though it is a newer feature and it may have less stuff than their other items."
"Datadog does not provide any free plans to use the solution. When I start with a proof of concept it would be sensible to have a free plan to test the tool and check whether it fits the requirements of the project. Before the production stage, it is always good to have a free plan with some limited features, number of requests, or logs."
"Our licensing fees are paid on a monthly basis."
"It has a module-based pricing model."
"The price is better than some competing products."
